Check Multiple Tests' Success at Once

[BowTiedDevOps]

Using a composite action to check that multiple jobs which are running tests are successful.

The called action is succeeding only if all the jobs parsed through the jobs input (JSON string of needs field) have success as status, otherwise it fails.

The purpose of implementing this step is to add the possibility of only making the job that calls the composite required in a ruleset check, instead of having each individual test required (i.e. each job from a matrix strategy).

Reference runs:

• Successful (no test failures): https://github.com/BowTiedDevOps/stacks-core/actions/runs/7978701647?pr=3
• Failed (4 test failures - check jobs also failing): https://github.com/BowTiedDevOps/stacks-core/actions/runs/7979062950?pr=4
• In both of these runs, Docker Image is failing because of a push authorization - the workflow is unchanged and only works with the secrets from stacks-network/stacks-core repository
